I'm not sure I understand the idea, but would that be something along
these lines? Adding a "nocomplete" category in commands-list.txt, to
do the opposite of the "complete" we already have[1]. Then adding a
new group name to "--list-cmds" (such as "--list-cmds=completeonly"),
which would include the commands that are in "complete" and exclude
those in "nocomplete"? We then might be able to complete subcommands
with the output of:

git --list-cmds=list-mainporcelain,others,nohelpers,alias,completeonly,config

[1]: "nocomplete" would only be relevant in conjunction with
"list-mainporcelain", as the commands in the latter (as gitk) are
currently completed by default (even without "complete").

In the list suggested by git-completion, I think gitk is the only one
(if I haven't missed any).
